One side wall is perpendicular to the rear wall. The other side wall is at 80 to the rear wall and is abbreviated to provide a limited lateral extension of material.

Patented Sept. 29, 1970 JAY/77170? A TATORNEYS FLOOR RESURFACING SPREADER BACKGROUND The invention pertains to implements for applying or spreading material.

Floors. such as concrete floors. are worn or deteriorated by heavy traffic, chemicals. weather and the like. Patching and resurfacing has been accomplished by applying a thin layer of sand-extended epoxy resin to the floor surface. In the past, screed bars of about Va" to /4 thickness have been set on the floor at approximately two foot spacing. The sand-extended epoxy resin is mixed, placed between two screeds. and leveled with a bull float. For a smooth surface, the surface may be troweled with a steel trowel. Alternate strips are constructed and. after drying time. the remaining strips are filled.

A faster means of applying the floor resurfacing material is desirable. Additionally, it is desirable to be able to apply adjacent strips without waiting the required drying time.

SUMMARY The present invention relates generally to implements and more particularly to a spreader for applying a resurfacing material on a floor.

A general object of the present invention is to provide a floor resurfacing spreader by which the resurfacing material may be applied more rapidly than heretofore.

Another object is to provide a floor resurfacing spreader which is arranged to apply parallel strips of material on the floor in contiguous relation.

These. and other objects and advantages of the present invention. will become apparent as the invention becomes better understood from the following description when taken with the drawing.

DRAWING FIG. I is a top view of a floor resurfacing spreader constructed in accordance with the present invention;

FIG. 2 is a front view thereof;

FIG. 3 is a side view thereof;

FIG. 4 is an enlarged fragmentary view of the rear corner of the spreader; and

FIG. 5 is a plan view of the spreader being utilized to apply a parallel strip of material contiguous to the first strip.

DESCRIPTION Reference is now made more particularly to the drawings which illustrate the best presently known mode of carrying out the invention and wherein similar reference characters indicate the same parts throughout the several views.

In FIG. 5 there is shown a floor 11 to which a strip I2 of resurfacing material is being applied parallel to a previously applied strip 13. The implement being utilized is a floor resurfacing spreader. generally designated 15. For simplicity, the floor resurfacing spreader will hereafter be referred to as a spreader. As will become apparent, the spreader is constructed and arranged to apply the second strip I2 contiguous to the previously applied strip 13 without messing or marring the previously applied material and without contacting the spreader to the adjacent strip 13.

The spreader 15 includes a rear wall 18. conveniently made of sheet metal. which has a material-spreading bottom edge 19 spaced above the floor. A backing structure 20 conveniently made of wood. is secured to the back wall 18 in any convenient manner to rigidify the same. A right side wall 24 and a left side wall 26 are adjustably mounted at opposite ends of the rear wall 18. Each side wall has a generally straight bottom edge which provides a floor-engaging runner.'The side walls 24 and 26 are adjustably mounted by means of fasteners 32 extending through slots 34 (See FIG. 4). into the backing structure 20. By loosening the fasteners 32. the height of the bottom edge 19 may be positioned at any preselected height to deposit the strip or layer of material on the floor II. For exampie, the thickness of the layer may be from about one-sixteenth inch up to one-fourth inch or more. The walls 16. 24 and 25 define an open bottom hopper for receiving the material to be spread. As can be seen, the hopper is also open at the top and front. Through the open top, a quantity of the material may be deposited preparatory to spreading, or while the spreader is in motion. A suitable material for use in the present invention is a sand-filled. or sand-extended. epoxy base resin which is readily available on the market. To deposit or extrude the material on the floor, the spreader 15 is pushed or pulled. For this purpose, a generally L-shaped handle 22 is mounted on the backing structure 20 (See FIG. 5).

Right side wall 24 is preferably mounted generally perpendicular to rear wall 18, as best shown in FIG. 1. The right side wall 24 extends rearwardly of the material-spreading bottom edge 19 to confine the edge of the material at that side of the spreader. As best seen in FIG. 4, right side wall 24. has a rear edge 24a disposed rearwardly of the rear wall for this purpose.

Left side wall 26 is adjustably mounted at the other end of the rear wall and preferably at an included angle of about thereto. Thus the side walls 24 and 26 are in non-parallel relationship. A support bar 28 interconnects the side walls 24 and 26 at the front thereof to hold them in the non-parallel relation. In other words. the front ends of the side walls are closer together than the rear ends. In this manner, the left side wall is at an angle of about l0 to the edge of a previously applied strip when the right side wall is parallel thereto. This allows the second strip to be extruded or applied closely adjacent the previously applied strip while maintaining the left side wall away from the previously applied material.

The left side wall 26 is also arranged to spread a small amount of the material laterally against the previously applied strip. For this purpose, left side wall 26 has a rear edge 26a which intersects the bottom edge at a point 26b no further rearwardly than the material spreading bottom edge 19 of rear wall 18. In the preferred embodiment illustrated. rear edge 26a is disposed at a rearwardly inclined angle from this point. As best seen in FIG. 4, material can be extruded or applied laterally between the material applying edge 19 of the rear wall and the rear edge 26a of the left side wall. In this manner, the shape of the side wall allows the material to be spread laterally contiguous to the previously applied strip while the construction of the spreader keeps the side wall 26 disposed away from the previously applied material.

In use. a guide line 40 (See FIG. 5) is placed or marked on the floor II a preselected distance from the edge 14 of previously applied strip 13. This preselected distance generally corresponds to the width of the strip ordinarily extruded or applied by spreader 15. The right side 24 is then guided along line 30 and the construction of the spreader assures that the left side wall 26 will not foul or mar the previously applied material.

It is now deemed apparent that the present invention provides a new and useful floor resurfacing spreader in which contiguous strips may be applied without touching the adjacent side wall to the previously applied strip. While a preferred embodiment of the present invention has been described, this has been done by way of illustration and not limitation. and it is to be understood that various modifications in structure will occur to a person skilled in the art.

lclaim:

I. A floor resurfacing spreader for spreading a viscous resurfacing material in parallel strips, and comprising: a generally bottomless hopper including a rear wall having ends. and laterally spaced side walls at opposite ends of the rear wall; each side wall having front and rear ends and a straight bottom edge adapted to ride on the floor". the rear wall having a material-spreading bottom edge spaced above the bottom edge of the side walls; means for holding the side walls in nonparallel relation with at least one side wall skewed inwardly so that the front ends are closer than the rear ends; said one side wall being at an acute angle to a line perpendicular to the back wall; the side wall opposite said one side wall extending rearand a line perpendicular to the back wall is about l0".

3. A floor resurfacing spreader as set forth in claim 1 wherein the rear wall slopes upwardly in a forward direction from its material-spreading bottom edge, and including means for adjustably mounting the rear wall for selectively changing the spacing between its material-spreading bottom edge and the bottom edge ofthc side walls.
